General Description

Endosulfan ether is a highly toxic and persistent organochlorine pesticide and insecticide. It is a mixture of two stereoisomers, alpha-endosulfan and beta-endosulfan, and is used to control a wide range of pests on crops such as cotton and vegetables. However, it has been banned or severely restricted in many countries due to its harmful effects on human health and the environment. Endosulfan ether is known to be a neurotoxin and has been linked to adverse effects on the nervous system, kidneys, and reproductive system. It is also highly toxic to aquatic organisms and has been found to persist in the environment for long periods of time, leading to concerns about its potential to accumulate in the food chain. Overall, endosulfan ether is considered a hazardous and environmentally damaging chemical with significant health risks associated with its use.

Comparative studies of various iron-mediated oxidative systems for the photochemical degradation of endosulfan in aqueous solution

This study investigated iron-mediated oxidative processes for the photochemical degradation of endosulfan, a chlorinated insecticide and central nervous system disruptor. At UV fluence of 360 mJ/cm2, 52.4% and 32.0% removal of 2.45 μM initial endosulfan was observed by UV/Fe3+ and UV/Fe2+ processes, respectively, at an initial concentration of 17.8 μM iron. The degradation of endosulfan by UV/Fe3+ or UV/Fe2+ was dramatically enhanced by adding peroxide (i.e., H2O2, S2O82- or HSO5-). Among the UV/peroxide/Fe processes, the highest degradation efficiency of 99.0% at UV fluence of 360 mJ/cm2 was observed by UV/HSO5-/Fe2+ with 2.45 μM [endosulfan]0, 17.8 μM [Fe2+]0, and 49.0 μM [HSO5-]0. The observed degradation rate constant of endosulfan was promoted either by increasing [Fe2+]0 and/or [peroxide]0 or by decreasing [endosulfan]0, while the initial degradation rate of endosulfan increased with increasing [Fe2+]0, [peroxide]0, or [endosulfan]0. At UV fluence of 6000 mJ/cm2, 45.0% mineralization as represented by the decrease in total organic carbon content was observed by UV/HSO5-/Fe2+ at 9.80 μM [endosulfan]0, 980 μM [HSO5-]0, and 17.8 μM [Fe2+]0. The major by-product of endosulfan was observed in all cases to be endosulfan ether which was further degraded with an extended reaction time. The results suggest that iron-mediated advanced oxidation processes (AOPs) have a high potential for the removal of endosulfan and its by-product from contaminated water.
